AppleScript is a programming language used on Apple Macintosh computers. Its main use is for writing small programs for automating repetitive tasks such as resizing a large number of images. One of the more powerful aspects of AppleScript is that it can control most Mac applications directly without user intervention. This makes it relatively easy to build script which, for example, retrieves data from a number of different websites, adds that data to a spreadsheet, performs some analysis and writes the result to a document.

The latest version of MS Office for Mac (2008) doesn't support Visual Basic for Applications (VBA) macros, so any processing that relies on those macros will not work with this release. AppleScript is the official replacement for these macros but manual conversion is required as there are no automated conversion tools.
